Laura Ingalls Wilder collaborated with her daughter on many books in the Little House on the Prairie series, and it wasn’t always a cooperative arrangement. A letter from 1938 suggests the scope of their creative frictions: “Here you have a young girl,” Wilder’s daughter wrote to her about one character, “a girl twelve years old, who’s led a rather isolated life with father, mother, sisters in the country, and you can not have her suddenly acting like a slum child who has protected her virginity from street gangs since she was seven or eight.”

What was in your average Soviet cosmonaut’s survival kit circa 1968? Among other specialties: three balaclavas, a tripartite rifle/shotgun/flare-gun, and a pistol intended to frighten “wolves, bears, tigers, etc.” in the event of a crash landing.

A new app called Cloak helps you “avoid exes, co-workers, that guy who likes to stop and chat—anyone you’d rather not run into.” Which makes life a bit more miserable, it turns out: “‘All Clear: There’s nobody nearby’ reads like such a strange, sad message, such a lonely thing to have achieved through technological control of our social environments. Looking at that screen makes me want to place my phone face down on my desk, go out into the street, and walk around until I bump into someone I know.”
